Brand new FSD Heat-Sync^TM kit, for all GM 6.5 Turbo Diesels with electronic fuel injection used in C/K trucks and Suburbans from 1994-2000. Manufactured in USA by SSDiesel Supply^TM, GM 6.5 TD specialists. Solves the problem of frequent PMD failure with your GM Diesel.

The PMD (pump mounted driver) is that small black box mounted on the side of your injection pump. It is a signal amplifier that powers the fuel solenoid. It contains 2-500 watt transistors which create a lot of heat. The factory mistakenly mounted this PMD module on the side of an already hot injection pump and in the engine valley below the intake manifold where temperatures skyrocket. As everyone knows, electronics do not like heat and they will fail prematurely. Symptoms of failure are stalling, hard starting, surging, poor fuel mileage, erratic idle and finally no-start. When they go it usually will not give any codes with the SES (Service Engine Soon) light. This American Made Cooler kit, relocates the PMD to a cooler area of the engine compartment, above the intake, on a massive oversized heat sink. A proven design. Our design has some distinct advantages over all the competition's. Please check our "advantages" section on our homepage and our FAQ section for details.

This kit includes everything INCLUDING a new OEM latest version BRAND NEW PMD to complete the installation. I also include a new #9 calibration resistor. (other resistors available upon request at no extra charge) The PMD and resistor will come pre-mounted to the cooler using industrial heat sink compound instead of a pad. (proven better heat transfer then any pad made) Included in this kit is 1) cooler as pictured, grade 8 mounting hardware (required to obtain proper torque for heat transfer), and industrial heat sink compound used in mounting PMD to SSD Heat-Sync. Also a brand new warranted PMD, and #9 Stanadyne calibration resistor, and complete step-by-step instructions. The original harness will plug right into module without modification and absolutely NO strain on wires. Only basic hand tools required. No drilling or cable splicing. Approximately a 10-20 minute installation. A truely simple Plug-and-play installation. See our warranty page for more info.

***WORD OF CAUTION*** Heat Transfer Technology is a science. The sizing of a heat sink requires calculations for the heat sink load of 2-500 watt transistors in an underhood environment exceeding 150DF. The mass of the heat sink, cooling fin design and cooling fin surface area are CRITICAL to PMD life. Although my "Heat-Sync" runs significantly cooler then most of the competitors, most others will still somewhat do the job. However, I see one out there with little to no "home made fins" that can't possibly dissipate the heat of 2-500 watt transistors. Temperature will fry your PMD again in short order. Look to buy the best functioning one, not the prettiest one. Extensive research and engineering have gone into my design. No guesswork involved!
